The hearts of elasmobranchs, Like those of other vertebrates, contain high concentrations of the yS-amino acid taurine, which is thought to play an osmoregulatory role in cardiac tissue. Although mammals and certain invertebrates can synthesize taurine from sulfur-containing precursors, e.g. cysteine, fish are unable to do so since they lack at least one enzyme involved in taurine biosynthesis: cysteine sulfinate decarboxylase (Jacobsen and Smith, 1968). Therefore, taurine must be acquired by… CONTINUE READING
